Cardioembolic ST-Elevation Myocardial Infarction in a Patient With Atrial Fibrillation and Polycythemia Vera.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
ST-elevation myocardial infarction (STEMI) is most commonly caused by acute atherosclerotic plaque rupture with superimposed thrombosis. Coronary embolism represents a rare but clinically important non-atherosclerotic mechanism of STEMI, which is frequently associated with atrial fibrillation and other prothrombotic conditions. Embolic STEMI has been associated with higher rates of adverse outcomes and requires a management strategy distinct from atherosclerotic disease. We present a 61-year-old male with paroxysmal atrial fibrillation and polycythemia vera who presented with anterolateral STEMI. Coronary angiography revealed occlusion of the distal left anterior descending and diagonal branches without underlying atherosclerosis, consistent with a cardioembolic etiology. He was managed with anticoagulation without stenting and discharged on long-term oral anticoagulation. This case highlights the importance of considering coronary embolism in patients with arrhythmias or hypercoagulable states presenting with STEMI. Early recognition allows avoidance of unnecessary coronary stenting, guides appropriate anticoagulation, and supports targeted strategies to prevent recurrent thromboembolic events.
